Pro Ultra Sonic Disc Pro Ultra Sonic Discs are the secret to creating tube flies with maximum movement and action. These discs sit at the front of your tube body, creating a current that allows materials on the tube to pulse, breathe, and undulate freely in the water—exactly what you want when you're trying to convince fish your fly is alive. Why Front Discs Matter When you tie materials like marabou, schlappen, or hackle those materials gain freedom of movement they wouldn't have otherwise. The disc allows water to flow through the fluted holes, allowing them to flow and pulse with every current shift and strip. The result is flies with lifelike action that triggers strikes from fish that have seen a thousand static patterns. Perfect For Intruder-Style Flies: Essential for creating that signature pulsing action on modern steelhead patterns Spey Flies: Allows hackle and marabou to breathe and move independently Steelhead Tubes: Creates separation between materials for maximum underwater movement Salmon Patterns: Traditional and modern tube flies with enhanced action Trout Streamers: Smaller tube patterns that need lifelike movement Pike & Musky: Big flies with materials that pulse and push water The Ultra Sonic Advantage They're sized to work seamlessly with the ProTube system, and the precision molding means each disc is identical—no wonky edges or inconsistent thickness that can affect your fly's action. Available in multiple and colors to match your tube diameter and fly design. Stock up—once you start using discs to enhance material movement, you'll wonder how you ever tied tubes without them.
